1 Claim.

This invention relates to change makers and has among its object and advantages the provision of an improved change making device, wherein a plurality of coins of predetermined denomination are arranged in a series of columns, in which novel means are provided for removing the lowermost coin in each column upon insertion of a coin of predetermined larger denomination and subsequent actuation of the device.

Coins of different denominations vary in size and an object of the invention is to provide a device which will pass the coins over a base partition having openings of predetermined sizes, through which the coins may drop according to their size.

The first openings being smallest will permit only dimes to drop through and since the other coins are larger they will pass over subsequent openings when projected forward until openings of corresponding sizes are reached at which time these coins will drop through such openings. Thus a device of this character requires the use of only one coin receiving slot to handle coins of different denominations.

With the above and other objects and advantages in view the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed, and illustrated in the accompanying drawings in which:

Figure 1 is a top plan view partly broken away of an embodiment of the invention;

Figure 2 is a sectional view on the line 2-2 of Figure 1;

Figure 17 is a sectional view on the line ll-Il of Figure 2 and Figure 18 is a bottom plan view of the chute plate shown in Figure 16.

Referring more in detail to the drawings the reference numeral 20 designates the cabinet which encloses the change making device except for the coin receiving slide and discharge trays which extend outwardly therefrom and the rod for manipulation of the coin receiving plate likewise extending outwardly from the cabinet.

The cabinet comprises front wall 22 and side walls 24 and the walls are provided with inset inner flanges 26 at the top thereof and marginal flanges 28 at the bottom thereof. The flanges 26 engage the depending lugs 29 on the removable top 30 and are secured thereto by fasteners 32 and a depending marginal flange 34 on the top engages the outer top edges of the walls. The flanges 2B lie flush with the removable bottom 36 and are secured thereto by fasteners 38 and the bottom is provided with the upstanding marginal flange 40 to engage the outer bottom edges of the walls.

The top at its rear edge is provided with depending lugs 42 which are parallel to but spaced from the flange 34 between which the removable back wall 44 is mounted at the top thereof and the bottom 36 is provided with upstanding lugs 46 which are parallel to but spaced from the flange 40 between which the removable back wall 44 is mounted at the bottom edge thereof. To apply the back wall, it is only necessary to insert its upper edge between the lugs 42 and flange 34 and slide the wall upwardly to clear the flange 40 and then pushed inwardly and allow it to drop between lugs 46 and flange 4B. The back wall is secured in closed position to the lock 48.

The top 30 is provided with coin receiving opening 50 through which coins of different denominations are deposited for change making purposes. A coin dropped through the opening 59 will fall on the chute supporting plate 52 provided with laterally extending apertured flanges 54 whereby the chute may be secured to the top 30 by fasteners 56 entering the parallel guide lugs 58.

3 The plate 52 is provided with a square shaped opening 69 for dimes, and the chute 62 communicates therewith, a square shaped opening 65 and communicating chute 66 for nickels, a square shaped opening 68 and communicating chute T6 for quarters, and a square shaped opening I2 and communicating chute I4 for half dollars, and the chutes are retained in alinement by the conforming bands 76 secured to the sides of the chute. The coin slide 18 having the upturned handle end 86 positioned intermediate the guide lugs 58 is provided with the bifurcated end 82 which communicates with the opening 56 to receive the coin and pushes the coin forward upon inward pressure on the end 80 to drop the coin through the appropriate square shaped opening. The slide 78 is provided with the pin 84 which engages the elongated slot 86 in the cover 36 to limit the movement of the slide during its withdrawal to receive a coin or its forward movement to drop the coin in its appropriate square shaped opening.

Coins from the chutes depending on their" de nomination are dropped into one of the battery of feeding mechanisms 88 positioned immediately below the end of the chute and are mounted on the partition 66 secured to inwardly extending lugs 92 on the front and sidewalls by means of fasteners 94.

The feeding mechanisms 88 comprise the parallel relatively spaced side walls 96 having lower marginal edge flanges 98 which are secured to the partition 90 by fasteners I96. The side walls 66 at approximately the center thereof are provided with outwardly extending lugs I62 in which are pivotally mounted'by means of the pins I04 the dogs or latches I86 having the inturned' upper ends I08 which extend inwardly of the walls 96 by means of oppositely positioned openings therein and openings I It intermediate the lugs I62 permit a tension spring IE2 to be connected to the dogs or latches I66 by means of eyes I I4 secured to the dogs I66. Immediately below and engaging the inturned ends I 68 is the plate II6 which is secured to the sidewalls-and the plate extendspartly beyond the center of the ends I08 to taper inwardly at I'I'B to the reduced downwardly curved end I23 and the remainder of the walls are retained in alinement by the transverse pin I22. Slidably mounted on the plate H6 is the coin actuator plate I24, having the depending flanges I26 recessed at I28 to receive the ends I68 of the dogs I 66 and provided with the longitudinally extending open ended slot I30 at'the center thereof which communicates with the semielliptical front end I32. Dogs I34 having upstanding ends I36 are pivotally mounted by pins I 38 on the undersurfa'ce of the plate I24 and a spring Ede connected to the dogs force the dogs inwardly into opposed seats I42 provided in the flange and plate I24. The plate at the rear thereof has a pin I4 3 in the center thereof to pivotally connect the link I 36 thereon. Secured to the side wallsare the stops I48 and I48, which overlap and have sliding engagement with the plate I24. The upper ends of the walls 96 are provided' with channel shaped guide flanges N52 to slidably' receive the coin pusher plate I54; there being one for each feeding mechanism and the plates are connected at their face ends in spaced relation to each other to the bar 55 which extends transversely of the cabinet, and a rod frame I58 connected to the ends of the bar extends at right angles therefrom parallel to the plates I541 A push rod I66 connected to the center of the bar I56 extends outwardly of the cabinet I and is 4 provided with a knob I62 for the manipulation thereof and a bearing I64 is provided in the front wall of the cabinet for the rod IBIL- When the bar and frame connected thereto are pushed inwardly by the rod the springs I66 will return the bar to normal position.

The plates I54 are provided with forwardly extending opposed parallel arms I68 having formed intermediately thereof the opposed parallel slots I'IG forming the extension I12 having the V- shaped end I14 and provided on the under surface of the extension with the V-shaped coin p'ushers I I6, and the rear end of each pusher I16 formed integral with the under surface of the plate enters its respective slot I36. It being understood that the size of the plates depends upon the denomination of the coins received therein, coins dropping from the respective chutes will drop on the plates I I6 whereon the knob I62 will be pushed inwardly until the coin is engaged by th'e'p'us'her I76. Continued forward movement of the coin will engage the dogs I96 releasing the plate I25, and when the coin engages the dogs I34 the plate I24 will be pushed rearwardly until the upturned ends I36 of the dogs I34engage the stops I48" at which time the coin will drop'into the cabinet. All of the plates I54- will move rear wardly' simultaneously but only the one carrying a com therein will actuate its plate I26 as pre'-" viously described.

The links I46 are provided with bifurcated end I76 which receive and are pivoted to the levers I86 by a pin I82 and the levers I are fulcruined at I84 on the bar I86 which is se' cured in brackets I86 on the inner surface of the side wall 24. The lever is pivoted in the bifurcated end IQ! of the link I96 by means of a pin E62 and the link has a threaded end I94 to re"- ceive the turn buckle I96 which has eng'agement with the threaded end we or the link 26c and the links and turn bucklesare kept in alinement by means of the sleeves 202 mounted on the bar intermediate of the fulcrums of the levers and the brackets I88. The bar is mounted into the brackets through apertures 264 in the sidewalls 24 and retained in one of the brackets by a pin 266.

The link 2010 has a bifurcated end 266 which is connected to a coin discharge plate 288 by a pin 2I6 and the plate is provided with suitable openings 2I2 for receipt of coins in change for the coin deposited. The plates 208 are slidably supported within the housings 2I4 secured to an enlargement 2 I6 formed on the inner surface of the front wall 2 by fasteners 2I8 engaging the flange 226 on the housings. The housings are provided with coin columns 222 which contain the proper denomination of coins which will be discharged as change in return ion the coin deposited.

Reading from left to right Figure 2 the first columns are for single quarters in exchange for a half dollar, the next two for two dimes and one nickel in exchange for a quarter followed by a column for two pennies and a second for three pennies in exchange for a nickel and the last two for one nickel each in exchange for a dime. The thickness of the plates 208 will be in accordance with the coins received therein and the coins will be deposited inthe coin discharge trays 224 by means of discharge opening 226 in the bottom of the housings 2 I 4. Thetray's-224 are formed on the front wall of the cabinet and extend out-- wa mly there'df. As the plate I24"- moves rearwardly it moves the correspondihglever I 86 rearwardly by means of the ends I46, the lever pushing the plates 208 forwardly by means of the links I90 and 200 and turnbuckle I96 discharge the change in the trays for the coin de-f posited.

Each unit as described, has had the operation thereof explained and it is believed that the in vention will be apparent to those skilled in the art.

A coin changer has thus been provided which by the use of one coin slot will receive and dis tribute and change coins of different denominations and it is to be understood that changes may be made in the details of construction, ar-

rangement and combination of the various parts 1 providing they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

A machine of the character described, comprising a cabinet, a coin receiving entrance in said cabinet, several coin feeding units disposed in said cabinet below said coin receiving entrance, means in said cabinet below said entrance for diverting a coin deposited in said entrance to one of said coin feeding units, a partition in said cabinet mounting said units in spaced relation to each other, each of said units comprising relatively spaced side walls, a first plate se- 3\ cured between said side walls and arranged ad-- jacent the upper edge of said side Walls, a first pair of spring tensioned dogs pivotally mounted on the side walls in opposed relation to each i ditional means on said pusher plate for engaging the diverted coin and causing the coin to engage the inturned ends and move the dogs out of the path of the pusher plate, a second pair of dogs pivotally connected to said coin actuated plate, said second pair of dogs being normally out of the path of movement of said pusher plate and nioveable by the diverted coin into engaging position with the pusher plate, and means for dispensing the coin at the inward movement of said pusher plate.
